# A body falls From a height of 200m if gravitional ceases after 2 sec find the further time required to reach grounf

after 2 seconds velocity is v

v = u+at

u=0 ,a=-g

v = -2g =-20m/s               (downward)

distance covered in 2 second = S

v2 = u2+2aS

u=0 , a=-g

S = v2/2a = 400/20 =20

it has covered 20 m so remaining distance from ground is 200-20 = 180m

now gravity there is no gravity effect so a=0

now we use speed = distance/time

t = d/v

distance = 180 ,velocity = 20

t = 180/20 = 9sec

thus body will take further 9 sec to reach the ground...

After travelling for 2sec the gravity ceases then the body will never reach the ground as there is no force pulling it down
